VAPOR AND AIR INTENSIFIER AND CARBURETOR ATTACHMENT.

Application filed. July 10, I922. Serial No.I573,S27.

To all whom it may concern:

Be it known that I, FRANK FREDERICK- WILLIAM DOERING, a subject of the King of Great Britain, and residing at I-Iibbing, in the State of Minnesota, one of the United States of America, have invented certain new and useful Improvements in Vapor and Air Intensifiers and Carburetor Attachments, of which the following is a specifition. 3

This invention relates to improvements in vapor and air intensifiers and carburetor attachments designed for use on automobiles and like vehicles, and the objects of the invention are to facilitate drawing a mixture of air and water vapor from a radiator. and

delivering the said mixture to' the carburetor in the proper proportions to form with the combustible fiuid a good explosive mixture; to deliver air to the radiator adjacent to the normal water level thereof, so that it will be beneath the water vapor, and thus cause a greater amount of water vapor to be delivered to the carburetor, and to so control the valve mechanism to permit of the carburetor functioning in the manner best calculated to increase its efficiency.

Further objects are to connect the carburetor with the radiator by means of flex- 30 ible conduit, so that, in the event of jarring taking place, there isno possibility of the conduit becoming broken, and undue vibration willnot be transmitted to the carburetor and interfere with the well working thereof, and generally to adapt the several parts to better perform the functions required of them.

With the above and other objects in View, the invention consists essentially of the improved construction particularly described and set forth in the following specification and in the accompanying drawings. In the drawings: Figure 1 is a side elevation of an automobile radiator showing the overflow pipe arranged to control the height of 'water line, and a conduit connecting the radiator and the carburetor through 'a three-way valve or cook, and water trap to prevent the water entering the carburetor.

Figure 2 is a vertical section of the radiator showing the position of the overflow pipe, air inlet pipes and vapor feed'pipes.

-Figure 5 is aside elevation partly in section of the air inletvalvel Figure 6 is a vertical section of the float chamber. i

Referring to the drawings, in which like characters of reference indicate corresponding parts in all the figures, and in which:

A'designates a radiator provided with an overflow pipe 10, the upper end of which extends into the radiator, while the lowerend projects below the radiator. This pipe when not: draining water from the radiator will help to deliver air thereto. B designatesa carburetor, of any well-known description; In accordancewithmv invention I provide a plurality of vertically disposed air inlet pipes 11 which extend through the top wall of the radiator A and. terminate just at the normal water line of the radiator.

In the space between the normal water level and'the upper wall of the radiator, a mixture of water vapor andair will be formed,

and this mixture isdelivered to a vapor pipe 12, the inlet end of which is'in the form of a gooseneck and extends through the rear,

wall of the radiator and upwardly into the highest point thereof. 7

The vapor pipe 12 is connected by aflexible conduit 13. to' a three-way valve 14, which is attached to the air inlet 15 of the carburetor B or the fuel intake as, found convenient. The valve 14 is controlled by a lever 16 actuated byarod 17 which extends through the dash board toa point adjacent to the driversseat.. A water trap 9 is pro- 1 vided adjacent to the valve l land isformed with an angularly disposed and upwardly extending battle wall-or shield 8 which pro-.

jects towards the flexible conduit 13, and below this baflie wall, a water chamber 7 js provided formed with a discharge out- When an automobile or engine equipped with this device is in use, the air whch passes through the overflow pipe 10 or the. air inlet pipe 11 is delivered into the radiator at a point adjacent to the normal water lever therein and below the water vapor, so that a good mixture of air and water vapor is obtained and delivered to. the vapor pipe 12.

This mixture of water vapor and air is drawn through a flexible conduit 13, the

. three-way valve 14 and into the carburetor B or manifold C, and is intermixed with the. motive fluid, so that the explosive mix:- ture delivered to the cylinder will consist of properly atomized combustible fluid,

I water. vapor and air, in the proportions N o best; calculated to. give proper results. water in the liquid state can pass the. baflie wall 8, so that the only water delivered to the carburetor from the radiator will be. in the form of water vapor suspended in the air which is. drawn through the radiator to the carburetor.

If it is. desired to supply'the engine with V replenishingthe radiator A with water, it

is. advisable that no. water could enter the vapor pipe 12 and, to this end, I provide a funnel 19 closed at the lower end and provided with a downwardly projecting flange 5 which embraces the bore of the said vapor pipe, and this funnel has perforations at in its side wallsjust: above the bottom wall, and through these perforations, the water poured into the funnel issues and is delivered to the radiator. In this way, the radiator A may be filled with water without any of the water entering the vapor pipe and without any serious drawbacks resulting from the filling operation which would otherwise occur if water entered the said vapor pipe.

Again, in some cases, the inlet of the radiator may be too small to accommodate the vapor pipe 12 therein, and, under such circumstances, I provide a vapor chamber or dome 21 having a threaded nipple 22 which screws on the inlet neck 22 of the radiator.

ing through the conduit 2% into the flexible conduit 13.

hen using the vapor chamber or dome, an adequate supply of water vapor and air will be obtained, and there is no possibility of water splashing or otherwise entering the nipple 24: so that the mixtureot' water vapor and air delivered to the conduit 13 will be in proper condition to be mixed with the combustbie fluid passing through the carburetor B.

In Figure. 5 Ihave illustrated an air inlet valve which is connected between the three-way valve. 14 and the water trap 9, as shown in Figure 7. The object of this valve is to permit air toenter intotheconduit 13 when the motor is running at high speed, and to. form a more accurate mix ture of moisture in proportion to the speed,

and to prevent heavy suction through theii.

conduit, 13. and pipe '11, which otherwise would cause water to. enter the motor. valve comprises a valve cage 2:7,. valve 28, spring 29., flat washer 30., and a nut, 31 for adjusting the tension on the valve to regulate the. amount of air. tobe let in.

D is the float chamber comprising a short vertical cylinder secured. to. the radiator A by a bracket 32. having; slotsv in, which aresecured. bolts with nuts. 33 whereby the chamber can be adjusted vertically, 3.4:- is a float in chamber D, and 35 is. a tube extending from the bottom of the chamber D to.

the top level of the. float. and; having: therein a needle, valve 36. This valve is suitably secured on the float and through the. holder 38 A water pipe 39. connectsthe. lower end of the float chamber to the radiator while. an air pipe 4-0. connects the. upper end of the chamber to the, radiator...

16. is apipe extending from. the bottom of the water tank 1 1 having its. end protected by a screen 41. A pipe, 42. having a check valve 43. connectsv the exhaust manifold 4A withthetank 1 1 for the purpose of obtain-- ing pressure in the, tank to. force, water through the pipe 16: into the float chamber is an opening in. the. tank l i for filling same. The tube 3.5 prevents. water from draining back to the tank 1 1 when there is no pressure in the tank. V hen the water in the radiator is lowered, the float chamber is drained off through a pipe 39, lowering.

the float 34: and raising the needle valve 36., thereby allowing water to pass through the. pipes 16 and 18 and up between the tube and valve 36.

hen the tank 1 B is full and the radiator A nearly full of water, and with the engine running it is obvious that a suction will be exerted bythe carburetor through the valve 14., If the valve is, so set as to cut off communication through the. conduit 13,,

then only air (through air inlet 18) will be drawn into the carburetor; but, if the valve This;

"is so set as to open or partly open the passage to the top of the pipe 12, then a partial will be carried to the carburetor.

It is found that the water in theradiator vaporizes so fast that it needs constant replenishing to keep its surface immediately under the ends of the tubes 11, and therefore the float chamber'D and auxiliary tank 1 f are provided. Of course ,When thewater surface in the radiator is high enough then the float 34 floats. lVhen the float lowers, then water will flow fromthe tank through the pipe "16 to the chamber and, because of the connections 39, the surface iii-both the chamber and the radiator will be 'equalized and raised. The necessary pressure' needed in the tank for feeding the water through the pipe 16 is created by the exhaust of the engine which passes up through the pipe 4L2. The check valve 43 prevents the escape of the pressure back through the pipe and enables a considerable pressure to be stored in the tank after the engine has stopped or is running at a very slow speed.

As the vaporization and replenishing of the water in the radiator is very rapid, it does not become hot enough to cause. steam. The moisture drawn to the engine is vapor, and this is found preferable to steam as the latter, when mixing with gas to be exploded, has already expanded to a considerable extent, while the vapor aids in the combustion by expanding when the gas is ignited and not before.

As many changes could be made in the above construction and many apparently different embodiments of my invention within the scope of the claims, constructed without departing from the spirit or scope thereof, it is intended that all matter contained in the accompanying specification and drawings shall be interpreted as illustrative and not in a limiting sense.

The mixture of water vapor andair is controlled by a three-way valve, which is so arranged that the outlet to the carburetor has at. all times a full opening. The inlets of the threeway valve from conduit 13 and air inlet 18' are so arranged that,

when 13 is half open, the air inlet 18 will also be half open or, if one opening is onefourth open, the other opening will be threefourths open; one will work in proportion to the other at any regulation.
